This study contributes with new information about the karyology in the family Haliotidae found in California Coast waters and gives some support the Thetys' model about biogeographical origin, from the Mediterranean Sea to the East Pacific Ocean.

A review about the biogeographical origin of the Family Haliotidae reported by Geiger & Groves (1999) using chromosome data in abalone showed that the abalones could be classified in three groups according to their chromosomes number.

This study contributed with new information about the karology in the family Haliotidae found in California Cost waters and supports the Thetys' model about biogeographical origin discussed by Geiger & Groves (1999) and Geiger & Poppe (2000).
